[Qemu-devel] using qemu to profile an application on a different target

[Bjorn Wesen]

Hi!

I was looking at qemu as a way of quickly trying compiled embedded linux 
user-space programs on an ARM target, which works nicely. An interesting 
possibility would be to be able to profile the emulated application while it 
is running in qemu. The most crude form would be an estimated total cycle 
counter, a better form would be the possibility to sample the emulated PC at 
a regular interval. 

I was looking through the documentation, mailinglists and parts of the code 
without finding any reference to any of this, so I was wondering if anyone 
on this list has any ideas if it's already supported somehow, or the 
strategy to add it in the best way to qemu(-arm). 

Regards,

Bjorn
